<u>Answer:</u> The equilibrium constant for the total reaction is 
<u>Explanation:</u>
We are given:

We are given two intermediate equations:
<u>Equation 1:</u> 
The expression of
for the above equation is:
![K_{c_1}=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=K_%7Bc_1%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
.......(1)
<u>Equation 2:</u> 
The expression of
for the above equation is:
![K_{c_2}=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K_%7Bc_2%7D%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
......(2)
Cubing both the sides of equation 2, because we need 3 moles of HI in the main expression if equilibrium constant.
![(41)^3=\frac{[HI]^6}{[H_2]^3[I_2]^3}](https://tex.z-dn.net/?f=%2841%29%5E3%3D%5Cfrac%7B%5BHI%5D%5E6%7D%7B%5BH_2%5D%5E3%5BI_2%5D%5E3%7D)
Now, dividing expression 1 by expression 2, we get:
![\frac{K_{c_1}}{K_{c_2}}=\left(\frac{\frac{[NH_3]^2}{[N_2][H_2]^3}}{\frac{[HI]^6}{[H_2]^3[l_2]^3}}\right)\\\\\\\frac{0.282}{68921}=\frac{[NH_3]^2[I_2]^3}{[N_2][HI]^6}](https://tex.z-dn.net/?f=%5Cfrac%7BK_%7Bc_1%7D%7D%7BK_%7Bc_2%7D%7D%3D%5Cleft%28%5Cfrac%7B%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D%7D%7B%5Cfrac%7B%5BHI%5D%5E6%7D%7B%5BH_2%5D%5E3%5Bl_2%5D%5E3%7D%7D%5Cright%29%5C%5C%5C%5C%5C%5C%5Cfrac%7B0.282%7D%7B68921%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%5BI_2%5D%5E3%7D%7B%5BN_2%5D%5BHI%5D%5E6%7D)
![\frac{[NH_3]^2[I_2]^3}{[N_2][HI]^6}=4.09\times 10^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNH_3%5D%5E2%5BI_2%5D%5E3%7D%7B%5BN_2%5D%5BHI%5D%5E6%7D%3D4.09%5Ctimes%2010%5E%7B-6%7D)
The above expression is the expression for equilibrium constant of the total equation, which is:

Hence, the equilibrium constant for the total reaction is 
Answer:
Astrology
Explanation:
One characteristic of science is that it must be reproducible. Other scientists must be able to repeat the original experiments and get the same result. That's what makes scientific claims reliable.
Astrology contends that the positions and motions of stars and planets can affect people and events on Earth. This has been disproved, so astrology is a pseudoscience
.
Biology, chemistry, and physics are sciences.
